GLOSSARY
Unique Cooling System
GXD-L65H1 GXD-L52H1
The display adopts a unique cooling system that
increases its reliability and versatility. Whereas
conventional systems bring cold air in from outside
to cool the unit, and then feed warm air back out,
this system uses multiple fans to circulate air inside
the processor unit, so that all heat generated in
the unit is effectively dissipated through advanced
heat sinks situated at the rear of the display.
Because the unit is completely sealed from external
air and there are no air intake filters to be cleaned,
the life of the LCD display is greatly extended.
This allows the display to be deployed in dusty
environments – such as train stations, shopping
mall entrances, and factories – where conventional
displays can often malfunction due to a build-up
of dust in their ventilation holes or on their cooling
fans. Alternatively, because this system does not
exhaust warm air, which was circulated inside the
unit and may contain dust, there is no need to
worry about contaminating air outside. This allows
the display to be used in environments where
extremely clean air is required – such as chemical
laboratories, food factories, and hospitals.

IPx4-rated Splash-proof Design
GXD-L65H1
The display adopts
a design meeting
the IEC (International
Electrotechnical
Commission) 60529 IPx4
standard* for reliable
operation in locations
where it may be splashed
with water. For this, various
considerations have been
taken into account in the design of the display
enclosure, for example, the connector protection
covers can be attached to the rear panel of the
display to help prevent water from leaking into the
connectors situated on the rear panel.
* To pass the test compliant with the IPx4 standard, the display is
Conventional System
IP5x-rated Dust-resistant Design
Thanks to its advanced
enclosure design and
unique cooling system,
the display is compliant
with the IEC 60529 IP5x
standard*, allowing for

splashed with water from all directions at a rate of 4.4 liters per minute
(L/min) for 10 minutes in power-off mode and no water damage
should be found in the display enclosure after being splashed. Sony
does not guarantee that the display will withstand operation in all
circumstances where water is present.

the IP5x standard, the display is
placed in a vacuum chamber
to depressurize the unit at up to 2 kPa and then talcum powder of
diameter less than 75 micron meters is blown in for 8 hours while in
power-off mode. No accumulated talcum powder, which may cause
the display to malfunction, should be found in the display enclosure
after the blowing test. Sony does not guarantee that the display will
withstand operation in such extremely dusty environments.
